UNITED STATES Water GUNNARD A. OBERG, OF JAMESTO'WbT, NEW YORK, ASSTGNOR TO BLACKSTONE MANU- FACTURING COMPANY, OF JAMESTOWN, NEW YORK, A CORPORATION OF NEW YORKv CYLINDER FOR WASHING MACHINES.

Application filed November 15, 1922. Serial Iil'o. 601,199.-

To all whom it may concern: Be it known that I, GUNNARD A. OBERG, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Cylinders for Washing Machines, of which the following is a specification, reference being had to the accompanying drawings, and to no the reference characters marked thereon,

which form a part of this specification.

This invention relates to metal cylinders and more particularly to that type of cylinders used-in washing machines.

The principal object of the invention is to use a light sheet metal, such as aluminum, both for the body, the ends and the lid or closure for the aperture in the body; and to so brace the same as to hold the parts properly together to form a durable structure.

Another object of the invention is to so construct the adjacent edges or meeting parts of the metal by proper seaming or bending that soldering or other fastening means will be unnecessary.

A further object of the invention is to so arrange and bend the sheet metal as to provide interior radial "clothes-engaging ribs extending longitudinally of the body of the cylinder,-the ribs and body portion being made of one piece of metal.

The invention consists in the devices and combination of devices illustrated, described and hereinafter set forth in the claims, and will be more fully understood as I proceed with my specification.

In the drawings.

Fig. 1 is a vertical, transverse, sectional view of a cylinder constructed in accordance with my invention, looking toward the inside of one end of the cylinder.

Fig. 2 is a detail sectional view, enlarged, of a portion of the cylinder, the section being taken longitudinally of the cylinder in the plane of the line 22- of Fig. 1.

Fig. 3 is a sectional view. on the same scale, of the parts shown in Fig. 2, the section being taken in the plane of the line 3-3 of Fig. 1. I

Figs. 4 and 5 are sectional views, also enlarged, of the end wall and that portion of the body adjacent thereto, which defines the edge of the opening through the cylinder, both sections being taken in the plane of the dotted line 4.4 of Fig. l, the latter with the lid in the closed position.

Fig. 6 is a perspective view, enlarged, partly in section, looking at the inside of the cylinder, to shoW more clearly the parts hereinafter described Fig. 7 is a sectional view, enlarged, showing the manner of connectlng the end wall with the body wall of the cylinder, the section being taken in the plane indicated by the dotted line 7-7 of Fig. 1.

Fig. 8 is a longitudinal sectional view of the cylinder taken in the plane of the dotted line 88 of Fig. 9.

Fig. 9 is an elevation of one end of the cylinder.

Fig. 10 is a sectional view of a detail, taken on the plane of the dotted line 10-10 of Fig. 9.

In said drawings, A represents the cylinder as a whole, comprising a cylindrical body portion 1, having a suitable opening 2 therein, a sliding lid or cover 3, and two end walls 4. Each end margin of the body portion is bent upon itself, as shown more clearly in Fig. 5, to form the thickened edge 5. Each end wall 4 is circular or disc shaped, as shown in Fig. 1, and is provided with an outwardly extending annular flange 6 which is bent or seamed at 7 and then turned in as shown at 8, so as to cover and surround the thickened edge 5 of the body 1. It will be observed by reference to Fig. 5, that the flange 6 fits nicely upon the inside of the inner surface or wall of the body 1,,while the extreme end 8 is pressed 1aggglnst the outside surface or wall of the The body 1 is a piece of rectangularly shaped metal, bent into circular form so as to make substantially three-quarters of the circumference of the cylinder when completed; the other quarter bein the opening 2 through the cylinder whic is covered by the sliding lid 3.

At four diametrically opposite points the body 1 is bent inwardly and then outwardl to form a double longitudinal rib 9. Each rib 9 carries interior y a bolt 10 which extends through the wall 4 and is suitably held by a nut 11 on the outside of the walls 4. Thus the body 1 and the two end walls 4, 4, are united and held together. The end walls 4, at the places where the edges of the ribs 9 contact therewith, are indented or bent outwardly as shown at 12 (Fig. 3) to form seats for the edges of the ribs 9.

The metal on the return looped portion of the two ribs 9 which are adjacent the opening 2, is bent upon itself as indicated at 13, to form a rounded or grooved margin 14, which two margins are parallel to each other and define the longitudinal walls of the opening 2. The end or circumferential walls of said opening 2 are defined by the rounded edges 15 of two strips. of metal 16, each strip being bent upon itself in the manner indicated in Figs. 4 and 6. The ma'or portion of each strip 16 is positioned tween the parts 6 and 8 of the two end walls and is also embraced by a part of the body flange 5. It will thus be understood that the strip 16 is bent 'so that its circumferential line will be continuous with the circumference of the cylinder body as shown in Fig. 1, the bent portions 6, 8, of the end wall embracing the thickened portion 5 of the body and also the strip 16.

On the inside of each wall 4, the metal is bent or pressed outwardly to form the panels indicated at 17, andit follows from this that on the outside of the wall 4, these panels are separated by the flat surface of the wall, thus forming a convenient space for a cast metaltrunnion bracket 18, the three arms of which bracket are suitably secured to the wall 4, as by the rivets 19.

That portion of the metal forming the two sides of one of the ribs 9 is spaced apart sufiiciently to embrace and frictionally hold a strip 20., the pro'ecting end of which extends outside of t e cylinder and is bent about itself to form a bead 21. This bead may hold a wire 22 if desired. The purpose of the head 21 is to afford a stop for the sliding door 3 to limit its outward movement when the openin 2 is exposed. Each end portion of the lid is rovided with an en gaging flange formed y bending the metal over and then under, as clearly indicated at 23, whereby the lid has a bearing upon and will readily slide over the flanges 6, 8, of the end walls 4. The longitudinal margins of the lid 3 are beaded as shown at 24, 25, by bein bent over wires 26, 27, respectively. It will be understood that when the door is .open, the beaded edge 24 will rest a ainst the bead 21 0f the body portion, the atter acting as a stop to limit the movement of the 11d; and that when the lid is swung to cover the opening 2, the beaded edge 25 will rest upon the bent over metal 13 ,so as to cover the margin 14 of the opening 2.

Usually a lock will be employed to hold the lid in closed position, but such being no part of the present invention, is not shown in the drawings.

I claim as my invention:
